Celiac.com 12/12/2016 - Studies suggest that celiac disease affects about 0.5% to 1% of the North American population. There is no good screening data based on small intestinal biopsy performed during routine endoscopic evaluation.
Dr. Freeman reviewed data from patients referred between January 1982 and December 2011 for evaluation of gastrointestinal symptoms, requiring elective investigative upper endoscopic evaluation, and who underwent duodenal biopsies to determine whether changes of adult celiac disease were present. He found a total of 9,665 patients, including 4,008 male and 5,657 female, who underwent elective endoscopy and duodenal biopsy.
Of these, 234, about 2.5%, showed celiac-associated physical changes, including 73 males (1.8%) and 161 females (2.8%). During the first 20 years, the number of biopsy-positive patients in five-year intervals progressively decreased, while over the next 10 years, the number progressively increased.
Dr Freeman's results indicate that celiac disease is far more common in specialist practice than has been suggested by data from healthy populations using serological screening.
Because endoscopic duodenal biopsy is so effective in spotting celiac-related damage, Dr. Freeman suggests it be routinely considered in all patients receiving elective endoscopic evaluation.
